Place half the vinegar into the pan with all the other ingredients.
Fit the lid and bring the pressure to the 2nd red ring. Adjust the heat
to maintain this pressure for 10 minutes. Allow the pressure to reduce
naturally - please refer to the instruction manual.

Remove the lid, add the remaining vinegar to the pan and boil until
the chutney thickens to the consistency of jam. Pour into warmed jars
and cover immediately.
